Tidy is not working for me. I've tried TS_TIDY as well as the built in TIDY that is configurable in the install tool. (not both at the same time :) I'm running on PHP 4.4 and my question is if this feature is dependent on PHP 5.0 which has Tidy built in or if it works with 4.4 as well? Do I need to install any scripts seperate from the extension?
